Wanhao 4s Z-Axis Preloader

thingiverse

I came across a DIY Z-Preloader designed for the CTC Bizer, so I decided to give it a try with my Duplicator 4s. Unfortunately, it didn't fit properly. Since there was noticeable movement in the Z-Axis, I took matters into my own hands and created my own version. To make it work, you need to attach two top pieces between the frame and the z-linear rails at the top, and another two at the bottom in the same location.
